MEDICAL DEVICE ENGINEER >>> PRO ATHLETE & Triathlon Coach
Coach Shangrila Rendon.
/// Coach Shangrila Rendon is a leading high performance triathlon/endurance coach, and athlete with over 20 years of experience.
She was a non-runner, non-cyclist, didn't know how to swim and had fear of open water.
/// From Medical Engineering to Triathlon Engineering—And Why That Matters 📊
Before diving into the triathlon world, I spent 15 successful years as a medical device engineer.
Why does that matter to you? Because my love for problem-solving, thinking out of the box, numbers, and data didn't stay in the lab—it’s integral to how I approach coaching. I left my thriving engineering career because I found something that allows me to use my analytical skills & passion to help people with a deep personal mission: transform busy high achieving individuals' lives to be the best person they can be through triathlon & endurance sports while staying injury free.
/// A Bit About Me and Why It Matters to You
I've navigated through some heavy stuff—battles with depression, PTSD, alcohol addiction, eating disorder, abuse and years of struggles that I wouldn't wish on anyone. But here's the transformative part: I discovered triathlon & endurance sports. They weren't just races; they were my lifeline.
Now, with the experience of having been recognized as a 2x Triathlon Guinness World Records Holder (2020 & 2015), Best-Selling Author, a Boston Marathon Qualifier, Ultraman & Ironman World Championship Kona Finisher, Ultra Athlete and High Performance Triathlon & Endurance Coach, my mission is to guide people like you through your own transformative experiences.
/// Why I Founded Feisty Fox Coaching 🦊
Our coaching isn't about turning you into a machine that only knows how to race. It's about making you the best version of yourself, on and off the course.
It's about smart, focused training that respects your time and your body. You're here to be incredible, but you also want a life outside the track, right?
We help athletes to have an amazing, enjoyable & memorable training & racing experience. I use the same analytical thinking from my engineering days and my strong drive that led me to be recognized with 2x Guinness World Records, in designing a game plan where your biggest dream goals become possible regardless of your current challenges.
